Ok so for the start of this thread, let's brainstorm on ways to keep those pesky caps on the battery bowls. So far, I haven't thought of anything. Anyone else? hahaha... No seriously though, I was thinking about a small rubber band maybe... but that would be a bit much I think. ***Update*** I fold-cut a small piece of a small paperclip roughly the length of the inside diameter of the battery bowl and simply placed it on top of the battery, underneath the cap. It takes a bit of playing with to get the cap to twist and lock under the flanges, but once it does it stays pretty tight. Maybe instead of a paperclip, a thin washer would do the trick. The next thing is guarding against the small distance it takes to untwist the cap... will update.
